Pokémon GO crowds on the National Mall (2016)

After Pokémon GO launched in July 2016, large groups of players gathered at the National Mall and its monuments to catch in-game creatures and visit virtual Pokéstops and gyms placed at landmark sites. News organizations and social-media users widely shared photos and videos of crowds playing around memorials such as the Washington Monument and the Lincoln Memorial. The phenomenon was covered as a notable example of augmented-reality gaming driving unusual public gatherings at prominent public spaces.
